'Will call Putin over pneumonic plague,' says Trump - what is happening in Russia?

Reports of a case of pneumonic plague at a research institute in Siberia have triggered international concern, with US president Donald Trump saying he plans to speak with Russian president Vladimir Putin about the case even as the World Health Organisation says the risk beyond Russia remains “very low”.The case emerged after a woman working at the Irkutsk Anti-Plague Research Institute of Siberia and the Far East died last week. Russian authorities said she had pneumonia of unknown cause, while reports in Russian media and on social media suggested she may have contracted pneumonic plague.There is, however, no confirmation that the woman died of plague.The WHO said Tuesday that it was in contact with Russian authorities following reports of her death.
